SPECIFICATION forming part of Letters Patent No. 438,332, dated October14, 1890.

Application filed December 27, 1889. Serial No. 335,156. (No model.)

To all whom it may concern:

Be it known that I, CLARENCE E. VAN AUKEN, a citizen of the UnitedStates, residing at Denver, in the county of Arapahoe and State ofColorado, have invented certain new and useful Improvements in Valvesfor Steam-Radiators; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the figures ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in valves for the radiators ofsteam-heating systems; and the object of my improvements is to provide acorner slide-valve whereby two apertures in the same levelone for theinlet and the other for the outlet of steam-may be opened or closed atthe same time and by the same action by the use of sliding disks orgates, said slides or gates occupying positions at right angles to eachother to correspond with the inlet and outlet apertures of thevalve-chamber, said device to be comparatively simple in construction,durable, easily operated, efficient, and reliable; to which ends myinvention consists of the features, arran gements, and combinationshereinafter described and claimed.

In the drawings is illustrated an embodiment of my invention, in whichdrawings- Figure l is an elevation of my improved valve. Fig. 2 is aVertical longitudinal section taken on the line 00 00, Fig. 3. Fig. 3 isa cross-section taken on the line y y, Fig. 2. Fig. 4 is a verticallongitudinal section taken on the line 2 .2, Fig. 3.

In the views let the reference-numeral 1 indicate a suitable shellinclosing the valvechamber 2, provided with the openings 3 and 4, oneforming the entrance for the steam to the chamber from the pipes and theother forming the exit for the steam from the chamber into the radiator.that these openings are on the same level, and that if horizontal linesbe drawn through their centers and produced within the chamher they willform right angles at their inter- Section.

It will be observed To the top of shell 1 is screwed or otherwisesuitably secured the cap 5, provided with a central aperture throughwhich passes the valve-stem 6. 1

Upon the interior of the central portion of cap 5, surrounding the stem,is formed a shoulder 7, which engages the upper surface of flange or rim8, formed upon the stem.

9 is a screw-cap having its thread ed portion screwed to the interior ofthe downwardly proj acting part of cap 5, the lower portion of saidscrew-cap being turned inwardly close to the stem and so as to engagethe under surface of the flange 8, which is permitted to turn freelywithin the recess formed by the engaging parts.

Surrounding the stem and screwed or otherwise suitably secured to thecap 5 is another screw-cap 10.

To the upper extremity of stem 6 is rigidly secured the hand-wheel 16,by means of which the valve is operated.

The lower portion of stem 6 is thread ed and enters a short tube 11, theupper portion of which is threaded for its reception. Tube 11 isprovided with two lugs 12 12-one opposite each of the openings 3 4. Eachof these lugs enters a recess in the back of a disk or slide 13. Theseslides are connected with the lugs in any suitable manner. They aresomewhat wedge-shaped and adapted to close tightly the openings 3 and 4when the tube -11 occupies its lowest position within the chamber 2,being the position shown in Fig. 2 of the drawings.

The interior of the lower portion of shell 1 is provided with a lug 14,beveled, as shown, and adapted to engage a corresponding projection 15,secured to tube 11. The object of lug 14 and projection 15 is to causethe slides 13 to close openings 3 and 4 tightly as tube 11 descends, lug14 acting as a guide for said slides and preventing the stem 6 and tube11 from being deflected toward lug 14 and away from openings 3 4 as thetube 1]. descends in closing the valve.

In describing the operation of my improved device I will suppose theparts to occupy the relative positions shown in Fig. 2. As stem 6 isturned,tube 11 rises on the stem and draws the slides 13 with it intothe upper part of chamber 2, thus opening the apertures 3 4. It will beobserved that stem 6 has a rotary movement, but no vertical movement ineither direction; also that as stem 6 is rotated tube 11 is drawn upwardon the threaded lower portion of stem 6. the action of stem 6 isreversed and tube 11 with the valves is forced downward into theposition shown in Fig. 2, projections 15 engaging lug 14, the wholemechanism wedging tightly into the lower portion of chamber 2, closingthe openings 3 4.

Having thus described my invention, What I claim is 1. In a valve forsteam-radiators, the combination, with a shell 1, inolosing thevalvechamber 2, provided with openings 3 and 4 on the-same level, of avalve-stem 6, having its lower portion threaded, a tube 11, threaded toreceive the lower portion of the stem, said tube being provided withaprojection 15, a lug 14, formed on the interior of the shell andadapted to engage part 15, slides 13 13, at-

In closing the valves 13 tached to tube 11 at right angles to each otherand adapted to close openings 3 and 4, substantially as described.

2. In a valve for steam-radiators, the combination, with a shell 1,inclosing the valvechamber 2, provided with openings 3 and 4 on the samelevel, of a valve-stem 6, having its lower portion threaded, a tube 11,threaded to receive its lower portion, said tube being provided with abeveled projection 15, a lug 14, formed on the interior of the shell,oppositely beveled and adapted to engage part 15, wedge-shaped sides 1313, suitably attached to tube 11 and located at right angles orapproximately at right angles to each other, said slides being adaptedto close openings 3 and 4, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
